And since the hometown Bruins offered, Johnson couldn't stop thinking about the local school.
So on Wednesday evening, Johnson called UCLA assistant coach Eric Yarber, the coach recruiting him, and told him he wanted to be a Bruin.
"I verbally committed to UCLA tonight," said Johnson. "I committed to Coach Yarber and he told me to call Coach (Jim) Mora.
Johnson shined at the UCLA camp this summer, working out at both receiver and defensive back and said that UCLA likes him on both sides, essentially recruiting him as an athlete.
Once the offer came, Johnson had been thinking about taking the Bruins up on the offer.
"It's been on my mind since the offer," said Johnson.
A one-time pipeline for the Bruins, it's been a few years since UCLA got a player from Crenshaw.
And in Johnson, they pick up a versatile two-way threat.
Johnson said Yarber, a Crenshaw alum, was thrilled with the commitment.
"Yeah he's excited," said Johnson. "I think it's safe to say I made his night."
